The purpose of this prospective cohort study was to assess the performance of tooth-supported, extended zirconia, fixed dental prostheses (FDPs). Thirty FDPs with span-lengths between 36 and 46 mm (mean: 40.33 mm), four to seven units and with connector dimensions of approximately 9 mm(2) were inserted (19 in the posterior region, 11 including anterior(More)
The purpose of this prospective cohort study was to assess the performance of tooth-supported, long-span, zirconia fixed dental prostheses (FDPs). Thirty FDPs with span lengths from 36 to 46 mm (mean 40·33 mm), with 4-7 units and with connector dimensions ∼9 mm(2) were inserted (19 in the posterior region, 11 including anterior teeth) using glass-ionomer(More)
PURPOSE To evaluate the fracture resistance of teeth restored using an adhesive core material placed under artificial crowns without pins or posts and to assess the effect of different preparation designs and cementation techniques (glass ionomer compared with adhesive cementation) used for the crowns. MATERIALS AND METHODS Eighty-three intact molars were(More)
This in vivo study investigated interexaminer reliability in the clinical measurement of L*C*h* values using a spectrophotometer (Shadepilot, DeguDent), which provides laminar measurement. Thirty incisors were measured by 3 trained clinicians. Intraclass correlation coefficient was used to assess reliability. Additionally, the range of differences between(More)
OBJECTIVES The purpose of this randomized clinical trial was to evaluate the clinical wear behavior of posterior, metal-free polymer crowns, with and without a glass-fiber framework, and to compare it with that of metal-ceramic crowns. METHODS Eighty single crowns manufactured from a newly designed polymer composite were set in posterior teeth. Half of(More)
To evaluate failure loads of teeth restored by use of alumina-coping, and to assess the effects of different amounts of residual tooth structure and different cements, standardized artificial alumina copings were fabricated on seventy-two molars. 24 of the copings were cemented by use of an adhesive resin cement (P-group), n=24 by use of glass-ionomer(More)
